The ifx_gl_wcswcs() function

Syntax

#include <ifxgls.h>
...
gl_wchar_t *ifx_gl_wcswcs(wcs1, wcs1_char_length, wcs2, wcs2_char_length)
        gl_wchar_t *wcs1;
        int wcs1_char_length;
        gl_wchar_t *wcs2;
        int wcs2_char_length;

wcs1

A pointer to the wide-character string to search for the substring wcs2.

wcs1_char_length

The integer number of characters in the wcs1 string. If wcs1_char_length is the value IFX_GL_NULL, the function assumes that wcs1 is a null-terminated string.

wcs2

A pointer to the wide-character substring to search for in wcs1.

wcs2_char_length

The integer number of characters in the wcs2 string. If wcs2_char_length is the value IFX_GL_NULL, the function assumes that wcs2 is a null-terminated string.

Usage

The ifx_gl_wcswcs() function searches for the first occurrence of the wide-character string wcs2 in the wide-character string wcs1.

Return values

gl_wchar_t *

A pointer to the first byte of the first occurrence of wcs2 in wcs1.

NULL

Either wcs2 was not found in wcs1 (the ifx_gl_lc_errno() error number is set to 0); or the function was not successful, and the error number is set to indicate the cause. See the Errors section.
